  2. Stretched tuning - Wikipedia

    en.wikipedia.org/wiki/Stretched_tuning

    Stretched tuning is a detail of musical tuning, applied to wire-stringed musical instruments, older, non-digital electric pianos (such as the Fender Rhodes piano and Wurlitzer electric piano), and some sample-based synthesizers based on these instruments, to accommodate the natural inharmonicity of their vibrating elements.

  4. Piano tuning - Wikipedia

    en.wikipedia.org/wiki/Piano_tuning

    A man tuning an upright piano. Piano tuning is the process of adjusting the tension of the strings of an acoustic piano so that the musical intervals between strings are in tune. The meaning of the term 'in tune', in the context of piano tuning, is not simply a particular fixed set of pitches. Fine piano tuning requires an assessment of the ...

    en.wikipedia.org/wiki/Piano_acoustics

    The Railsback curve shows how a piano tuned to compensate for inharmonicity deviates from theoretically correct equal-tempered tuning. The Railsback curve, first measured in the 1930s by O.L. Railsback, a US college physics teacher, expresses the difference between inharmonicity-aware stretched piano tuning, and theoretically correct equal-tempered tuning in which the frequencies of successive ...

  6. Keyboard matrix circuit - Wikipedia

    en.wikipedia.org/wiki/Keyboard_matrix_circuit

    A keyboard matrix circuit is a design used in most electronic musical keyboards and computer keyboards in which the key switches are connected by a grid of wires, similar to a diode matrix. For example, 16 wires arranged in 8 rows and 8 columns can connect 64 keys—sufficient for a full five octaves of range (61 notes).

  7. Piano key frequencies - Wikipedia

    en.wikipedia.org/wiki/Piano_key_frequencies

    For other tuning schemes, refer to musical tuning. This list of frequencies is for a theoretically ideal piano. On an actual piano, the ratio between semitones is slightly larger, especially at the high and low ends, where string stiffness causes inharmonicity, i.e., the tendency for the harmonic makeup of each note to run sharp.

  9. Pseudo-octave - Wikipedia

    en.wikipedia.org/wiki/Pseudo-octave

    The stretched octave, for example 2.01 : 1 , rather than 2 : 1 (an 8.6 cent pitch difference), sounds out of tune when played with ideal harmonic overtones, but in tune when played with lower notes whose overtones are themselves naturally stretched by an equivalent amount. In piano tuning, stretched octaves are commonly encountered in ...
